Significance and Use
This method is used to determine the force required to rupture textile fabric by forcing a steel ball through the fabric with a constant-rate-of-extension tensile tester.
This is a new method and therefore the history of data is very small, however the agreement of within- laboratory data suggest this method may be considered for acceptance testing of commercial shipments with caution.
If there are differences of practical significance between reported test results for two laboratories (or more), comparative test should be performed to determine if there is a statistical bias between them, using competent statistical assistance. As a minimum, samples used for such comparative test should be as homogeneous as possible, drawn from the same lot of material as the samples that resulted in disparate results during initial testing, and randomly assigned in equal numbers to each laboratory. Other fabrics with established test values may also be used for these comparative tests. The test results from the laboratories involved should be compared using a statistical test for unpaired data, at a probability level chosen prior to the testing series. If bias is found, either its cause must be found and corrected, or future test results for that fabric must be adjusted in consideration of the known bias.
1.1 This test method describes the measurement for bursting strength of woven and knitted textiles taken from rolls of fabric or fabric taken from garments.
Note 1—For the measurement of bursting strength with a hydraulic or pneumatic machine, refer to Test Method D3786. For the measurement of the bursting strength by means of a ball burst mechanism, refer to Test Method D3787
1.2 The values stated in either SI units or U.S. customary units are to be regarded as standard, but must be used independently of each other. The U.S. customary units may be approximate.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
